ShipFence helps merchants enforce shipping restrictions for regulated products like alcohol, CBD, and vape. Create rules by product, collection, or tag, then choose which US states or ZIP codes to block. When a customer checks out with a restricted address, the order is blocked with a clear message before payment. Restrictions run inside Shopify checkout, so they still apply when customers use Buy Now or express checkouts, and they keep working when you change your theme.

• Block checkout by US state or ZIP code for any product, collection, or tag.
• Restrictions apply inside checkout, including Buy Now and express checkouts.
• Ready-made rule templates for alcohol, CBD, and vape and tobacco products.
• Logs every blocked checkout with product, address, and reason for audits.
• Bulk import and export rules via CSV to migrate or back up your config.
